[cisco-voip] Wrong Time on Phones

[Carter, Bill]

UCM 7.1.3.31900-1
7962 SCCP Load 8.5(3)
 
CallManager is sync'd with a public NTP server and displays the correct time with timezone. (verified with show status and utils ntp status)
 
I have a Date/Time Group configured with CST GMT - 6:00. The Device pool has this Date Time Group.
 
All of the phones time is 6hrs off. They display GMT time. I have created other Date/Time groups with different offsets and the time on the phones never changes from GMT.
 
Ideas? This is a new 7.1.3 install, not an upgrade from 5.1.3.
